How Do I Accept That People Just Don't Care?

I'm a 34 year old woman and I have massive anxiety. I push it aside as best I can during social situations, especially social events which involve other parents from my daughter's school. I find I'm always the one to ask questions and try to keep the conversation flowing. It always gets awkward and I just kinda say bye and move on. I have realized people never try to keep conversations going with me. They never ask me questions or show any interest in me when I try so hard to connect with them. What's wrong with me? How do I accept that I'm just a person people aren't interested in? It's crushing because I have so much love to give others. They just don't want it :(
